Raman spectroscopy is shown to be useful as a tool for long‐term stability studies. The stability of a novel submicron‐size γ‐polymorph form of the explosive HMX (octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine) was monitored up to 1 year using Raman spectroscopy. The preparation and characterization of this submicron HMX has been previously discussed. It is important to know the long‐term stability of this submicron γ‐polymorph material under ambient conditions for its eventual utilization. This submicron HMX material has been found to be stable both chemically and polymorphically (to the order of 1% impurity level), even though HMX normally converts to the β‐polymorph at ambient conditions.
